IPA File Size vs On Device Storage Space Usage

I have created a game where the IPA file is around 25mb. When I look at my iPhone5 under Settings > General > Usage I see that the game is using 177mb of space.

Why is my game using so much more storage space than the IPA? I understand the IPA is a compressed file, but expanding out to 7 times the original size seems really weird.

When building the XCode project from the Unity editor, I only selected the used scenes in the game. Does this build process ignore any assets or scenes that are not used? For example demo scenes from plugins that are not part of the final game?

You can check from editor log what assets are taking the storage space in IPA

I was about to post the same question.

I use a couple of packages that show exactly what the size is and what assets are being used, but the size is way way under what ends up being on the device.

What gives with the xcode build that is blowing out the size?
I just want the smallest app possible for something fairly simple but it gets bloated on the xcode build different from that the Unity build size says it is.
